That means this breaker handles high-fault utility feeds at low voltage but is still usable on 480 V systems with moderate available fault current. No trip indicator or voltage trigger on this variant, so don't plan on local fault annunciation from the breaker face. The 3VA1125-5EF32-0BC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 3-inch width (76.2 mm) is the standard 3-pole MCCB footprint — it fits the same DIN-rail or screw-mount slots as other SENTRON 3VA1 breakers. If you're swapping out a competitor's 3-pole MCCB, check the mounting hole pattern; Siemens uses a 90 mm center-to-center on the base, which is common but not universal.","metaTitle":"Siemens 3VA1125-5EF32-0BC0 SENTRON MCCB, 25 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1125-5EF32-0BC0 SENTRON molded case circuit breaker, 25 A, 3-pole, 187 kA at 240 V.

Pricing and stock are confirmed at quote time through independent distribution — no automated figures here, but the spread is competitive and ship times are reliable."},{"question":"What is 3VA1125-5EF32-0BC0's listed depth (70 mm) on this component line?","answer":"The depth is 70 mm (2.76 in). That's the body depth excluding any handle projection or accessory protrusions — enough to fit most standard 200 mm deep enclosures."},{"question":"What is 3VA1125-5EF32-0BC0's listed width (76.2 mm) on this component line?","answer":"The width is 76.2 mm (3 in). That's the standard 3-pole MCCB width — it will occupy one 3-pole slot on a DIN rail or panel-mount footprint."},{"question":"Will 3VA1125-5EF32-0BC0 drop into a panel that was specified around 5SQ2370-2YA05 without rewiring?","answer":"The 5SQ2370 series is a different Siemens MCCB family (older 3WL or 3VL generation). The 3VA1125 has a different mounting hole pattern and terminal layout — you'll need to verify the footprint and busbar connections before assuming a direct swap. The 76.2 mm width is common, but the depth and terminal positions may differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1125-5EF32-0BC0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1125-5EF32-0BC0 when reusing this data.
